Il a construit une maison de génie en Alsace

Summary

The script narrates the innovative design of a house by Eric Vasseur, sculpted by the sun's daily trajectories. Named 'héliodom', the Alsace-based house is energy-efficient, staying cool in summer and warm in winter. With geometrical sun paths determining its structure, it achieves up to 80% energy savings. Vasseur, who won the Lepine contest in 2003, has since built similar domes in France, Switzerland, and Germany, challenging the traditional fixed view of the sun and embodying the spirit of the '60s dreams of the future.

Takeaways

• 🏠 The house is designed to be sculpted by the sun's trajectories, embodying the idea of writing the history of the past.
• 🌞 The concept of the house, called 'héliodom', was invented by Éric Vasseur, a designer and inventor from Alsace, France.
• 📐 The construction of the house took a year and was preceded by 10 years of planning and designing, including geometric studies of the sun's paths.
• 🌡️ The house maintains a comfortable temperature throughout the year, staying cool in summer and warm in winter due to its unique design.
• ☀️ The house benefits from total sun exposure during the winter months and is shaded during the summer, creating a natural temperature regulation system.
• 🔢 In extreme temperatures, the house maintains a significantly cooler temperature in summer and a warmer one in winter compared to the outside.
• 💡 The building design achieves around 80% energy savings, utilizing the sun's natural heating and shading to maintain a stable indoor climate.
• 🏢 The size and placement of the windows are crucial, allowing the sun to heat the building's facade in winter and providing shade in summer.
• 📐 The building's shape is determined by the sun's trajectory throughout the year, with different angles for summer and winter days.
• 🏆 Éric Vasseur won the Lepine contest in 2003 and has since built about ten different dome-shaped houses in France, Switzerland, and Germany.
• 📝 Vasseur patented the concept to prevent others from restricting its use, emphasizing that the idea is a natural one, not purely an invention.

Q & A

What is the concept behind the design of the house described in the script?

The house is designed based on the sun's trajectory, sculpted to optimize natural light and temperature control throughout the year.

Who is Eric Vasseur and what is his contribution to the house's design?

Eric Vasseur is the inventor of the house's design concept. He named it 'héliodom' and is a designer who conceived the house in his village of Kosswiller in Alsace.

How long did it take to go from the initial idea to the construction of the house?

It took 10 years from creating a small paper model to starting the construction work.

What is the significance of the geometrical trajectories of the sun in the house's design?

The sun's geometrical trajectories were used to determine the house's layout, ensuring optimal sunlight exposure and temperature regulation in different seasons.

How does the house maintain a comfortable temperature inside regardless of the outside temperature?

The house is designed to stay cool in the summer and warm in the winter by utilizing the sun's trajectory for natural heating and cooling, along with the building's mineral content for thermal inertia.

What are the energy savings achieved by the house's design?

The house can achieve up to 80% energy savings due to its efficient use of sunlight and thermal properties.

How does the size of the windows contribute to the house's temperature regulation?

The size of the windows is designed to maximize sunlight exposure in winter for heating and minimize it in summer to prevent overheating.

What is the difference in temperature between inside the house and outside during extreme weather conditions?

During summer, when it's 40 degrees Celsius outside, the inside temperature is around 22-24 degrees Celsius. In winter, when it's -10 degrees Celsius outside, the inside temperature can be around 20-23 degrees Celsius.

How many similar dome-shaped houses has Eric Vasseur built since winning the Lepine competition in 2003?

Eric Vasseur has built about ten different dome-shaped houses for individuals in France, Switzerland, and Germany.

What does Eric Vasseur believe about the sun's position in the sky and its impact on the house's design?

Eric Vasseur believes that the sun is not a fixed point in the sky but has a trajectory that changes daily, which has been considered in the house's design to sculpt the volume.

How does Eric Vasseur view his role in the creation of this house?

Eric Vasseur does not see himself as an inventor but rather as someone who has expressed something that already exists in nature and has simply utilized it through his design.
